What did Pioneer 11 discover about Saturn?
Pioneer 11 detected Saturn’s bow shock on Aug. 31, 1979, about 932,000 miles (1.5 million kilometers) out from the planet, thus providing the first conclusive evidence of the existence of Saturn’s magnetic field. The spacecraft crossed the planet’s ring plane beyond the outer ring at 14:36 UT Sept.
Are we still contacting with Pioneer 11?
The Pioneer 11 Mission ended on 30 September 1995, when the last transmission from the spacecraft was received. There have been no communications with Pioneer 11 since. The Earth’s motion has carried it out of the view of the spacecraft antenna. The spacecraft cannot be maneuvered to point back at the Earth.
How long did Pioneer 11 take to reach Saturn?
With a helping hand from Jupiter’s gravity, Pioneer 11 soared toward Saturn. It was a nearly five-year wait until the spacecraft was able to get to the planet, some 930 million miles from Earth.
Where is Pioneer 11 now?
Pioneer 11 is still sailing away from Earth, even though its transmission was received on September 30, 1995. As far as scientists know, the spacecraft is still moving outward – in the general direction of the center of our Milky Way galaxy – that is, generally in the direction of our constellation Sagittarius.
What was the goal of Pioneer 11?
Goals: Pioneer 11 was the first mission to explore Saturn and the second spacecraft in humanity’s early reconnaissance of the outer solar system. The spacecraft carried instruments to study magnetic fields, the solar wind and the atmospheres, moons and other aspects of Jupiter and Saturn.
What did Pioneer 11 accomplish?
Pioneer 11 discovered a small moon and an additional ring around Saturn. The spacecraft traveled underneath the ring plane taking beautiful pictures of Saturn’s rings. It also took measurements of Saturn’s magnetosphere, magnetic field and largest moon, Titan.
How long did it take for Pioneer 11 to reach Jupiter?
21 months
Right: Image of Saturn taken by Pioneer 11 after its successful flyby. Planned for 21 months of operations, just long enough to reach Jupiter and study the giant planet, Pioneer 11 ended up making the first remote observations of Saturn and operating for more than 22 years.
When did Pioneer 11 reach Jupiter?
As originally conceived, Pioneer 11 was intended as a backup to Pioneer 10 that launched 13 months earlier and was already through the asteroid belt, the first spacecraft to travel beyond the orbit of Mars, and on its way to the very first encounter with Jupiter in December 1973.
How long did Pioneer 11 last?

What part of Mars is curiosity exploring?
the Gale crater
Curiosity is a car-sized Mars rover designed to explore the Gale crater on Mars as part of NASA’s Mars Science Laboratory (MSL) mission.
How long will pioneer last?
The mission was a spectacular success and the spacecraft notched a series of firsts unmatched by any other robotic spacecraft to date. Originally designed for a 21-month mission to fly by Jupiter, Pioneer 10 lasted more than 30 years.
What did Pioneer 10 and 11 accomplish?
Highlights. NASA’s Pioneer 10 mission launched on March 2, 1972, followed by Pioneer 11 on April 5, 1973. Pioneer 10 is credited with being the first spacecraft to traverse the asteroid belt and fly by Jupiter. Pioneer 11 was the first probe to do a flyby of Saturn.
How many pictures did Pioneer 11 take of Saturn?
On Sep. 1, 1979, Pioneer 11 passed within 13,000 miles of Saturn’s cloud tops at a velocity of 71,000 miles per hour. During the encounter, it sent back data on the planet, its rings, and its satellites, including 440 images.
What is the Pioneer 11 spacecraft?
An artist’s impression of a Pioneer spacecraft on its way to interstellar space. Pioneer 11 (also known as Pioneer G) is a 260-kilogram (570 lb) robotic space probe launched by NASA on April 5, 1973, to study the asteroid belt, the environment around Jupiter and Saturn, solar winds, and cosmic rays.
What was the first spacecraft to study Saturn?
NASA’s Pioneer 11, a sister spacecraft to Pioneer 10, was the first spacecraft to study Saturn up close. The mission ended in 1995 and Pioneer 11 is on a trajectory to take it out of the solar system. Pioneer 11 is one of five spacecraft on a trajectory that will take them out of our solar system.
What happened to Pioneer 11?
After leaving Saturn, Pioneer 11 headed out of the solar system in a direction opposite to that of Pioneer 10, toward the center of the galaxy in the general direction of Sagittarius. Pioneer 11 crossed the orbit of Neptune on Feb. 23, 1990, becoming the fourth spacecraft—after Pioneer 10, Voyager 1 and 2—to do so.
